Oracle Forms

hi,

i have created A basic STUDENT form with all fields and the STUDENT/COURSES master/detail form .

I am trying to place to button on the STUDENT form that when pressed, will call the STUDENT/COURSES form and automatically query the COURSES for the employee being viewed on the STUDENT form.

here is the code i used

DECLARE
pl_id ParamList;
BEGIN
pl_id := Get_Parameter_List('tmpdata');

IF NOT Id_Null(pl_id) then
Destroy_Parameter_list (pl_id);
end if;
pl_id := create_parameter_list ('tmpdata');
add_parameter (pl_id, 'students_id',text_parameter, :s_id);
run_product (forms, 'C:resubmission\stucourse.fmb', synchronous, runtime,
filesystem, pl_id, null);
end;

although it successfully compiled,

when i press the button on the form it is giving me

frm-92101 : there was a failure in the forms sever during start up...

i have tried everything i can think off, am fairly new to this

please any assistance will be appreciated. am using oracle 10g

thanks in advance.
